The code below calls a PHP file for a true or false text result using the dojo.xhrGet method. When I load the PHP file by itself (replacing the $variable = $_GET("passedVariable"); with a hard-wired value), it correctly generates a "true" or "false" in my browser window. However, when I run the call in my larger web app, it returns the PHP source code instead of the results of my database query. Using JQuery's .get() method, I receive a XML object.
